The Hot Rolling Process - California Steel

finishing mills, which will roll the steel in tandem with one another. The workhorse roughing mill has 135" wide rolls for rolling 'broadside' (as the first roughing mill is commonly called) to make a slab wider. A 5,000 hp motor drives 42"-diameter work-rolls through 28:1 gears to reduce the slab's thickness by as much as 2-½".

Roll Separating Force - an overview | ScienceDirect Topics

The roll separating forces obtained in a single-stage pass of 55% reduction and two two-stage passes of 14/39% and 20/33.6% reduction are given in Figure 15.4, measured when rolling the softer AISI 1008, deep-drawing quality steel. Figures 15.2 and 15.4 are quite similar. The dynamic response of the mill is also similar to the previously observed behaviour.
